Pre-stacking in milk technology refers to the process of allowing milk to sit undisturbed for a period of time before further processing. During this time, the cream naturally rises to the top of the milk due to differences in density. This separation of cream from the milk allows for easier removal of the cream to create products like skim milk or different fat content milks.
